To all whom. 'it ma/y concem. E

Be it known that I, GEORGE W. NELL, of Philadelphia, i'n the county of Philadelphia, and State of Pennsylvania, have invented -anewp and improved Window-Shade Fixture; and I do hereby declare that the following is afull, clear, and exact description thereof', which will enable those ,skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part lof `this speciiication, in which- Figure 1 is a ture; v v

Figure 2 is a horizontal section of the same, taken onthe line x ,fg. l; i

parts. n

rIhis invention relates-to an improved cord-tightener for window-shade xtures; and

It consists in the combination ofthe hook with the toothed plate, when the latter is grooved longitudi-1 nally to receive a pin or rib formed upon the hook for the `purpose of preventing the same from being moved laterally upon the plate, and thereby displaced.

The following are some of the advantages of myrim` proved ixturez It can be easier set `than the ordinary fixtures, oc-

` cupiesless room, and isshorter, and has, nevertheless,

a longer space for 'adjustment than the same; the'hook `cannot be lost Aafter having 4been applied, even if the cord should break, and it is much cheaper than any of the other xt'ures, as both pieces of which it consists can be cast.

It has, at'its ends, two depressed ears or fasteningplates, a, by means .of which it canv be secured to the sidelview of my improved shade-.fixe

Similar letters of reference indicate correspondingl window-frame, so that the body' of the plate projects from the frame, as shown. v

The inner face of the plate A is toothed nearthe y* edge, or entirely, as indicated in figs. 'l and 2. v

B .is an Sfshaped hook, having one end forked to slide on and fit over the plate A, as shown.

The cord OA is fitted over the outer part, b, of the hook, in -the manner indicated in fig.v 1, while the inner ends, c, of the hook. t against the teeth, d," of the l plate. Y v A The hook is thus, by the teeth, held in any desired position, the cord drawing its ends, c, firmly against them; but if desired, the hook can be easily adjusted. A groove maybe formed in the outer face of the plate A, and a pin, e, from tlie hook, may fit into the same, as in g. 2, to prevent lateral play of the hook.` I am aware that the device illustrated in igs. 3 and 4 has already been in use. v

In this device, a slotted plate, A', is used, together with a hook, "B, said hook having a head, f, at its inner end, which it tted through the'slotas shown, to

engage in the teeth of the plate. 1

In this device, th'eplate A is not only tooweak, but

Y also the shank of the hook lacks suflicientstrength,

andthe hook is` liable to be lost, and to lateral play, all of which inconveniences are overcome by my invention.

A friction-roller may be arranged on the arm b of the hook B, when the cord is fitted over the same..

I claim as new, and desire to secure by Letters Patent- The combination of the S-shaped hook B with the toothed plate A, when the latter is providedwith a longitudinal groove to receive the rib or pin, e, formed upon the hook for the purpose of preventing the lateralplay of the same, as herein shown and described.
